Final answer:
Differentiating soda water, milk, and muddy water involves examining homogeneity, where soda water is homogeneous, milk is colloidal, and muddy water is heterogeneous. Filtration shows that solids in muddy water are retained while soda water and milk pass through unchanged. The Tyndall effect is observed in milk and muddy water but not in soda water.
Step-by-step explanation:
To differentiate between soda water, milk, and muddy water in terms of homogeneity, filtration, and the Tyndall effect, we need to understand the properties of each mixture.
Homogeneity
Soda water is a homogeneous mixture because the carbon dioxide is uniformly dissolved in the water. On the other hand, milk is a colloid which may appear homogeneous but microscopic examination reveals fat and protein globules dispersed in water. Muddy water is a heterogeneous mixture; it has solid particles of dirt and sand suspended in water, which eventually settle down if left undisturbed.
Filtration
Filtration is a technique that can separate the components based on particle size. Soda water will pass through a filter unchanged as it is a solution. Milk may pass through a filter without significant change too because the fat and proteins are too small to be caught by regular filter paper. However, the solid particles in muddy water will be trapped by the filter, leaving the water to pass through, demonstrating its heterogeneity.
Tyndall effect
The Tyndall effect is observed when light passes through a colloid and is scattered by its particles. Soda water will not exhibit the Tyndall effect as it is a true solution. Milk will scatter light to some extent due to its colloidal nature. Muddy water will strongly scatter light, providing further proof of its heterogeneous nature.
